Description

Technical area

The present utility model relates to a lifting sling, in particular a high-strength ring-shaped sling, which belongs to the technical field of slings.

State of the art

Lifting slings are connecting straps for mechanical lifting and are usually used in large projects. Synthetic fiber slings are divided into two categories: flat slings and round slings. The flat sling consists mainly of nylon fibers, polyester fibers and polypropylene fibers. They have their own characteristics and are suitable for different environmental occasions, but slings made of different materials should not be mixed. The material of the round sling is mainly made of synthetic polyester fiber, the outer layer uses a round polyester sleeve as a protective layer and the inner core uses a continuous 100% polyester core yarn to carry the lifting load.

When using a sling, the edge of the sling tends to have the most tension. When the objects hanging from the loop are sharp, the edges of the loop are often torn first, which can lead to production accidents. In addition, the size of the loops formed by the conventional annular loop often cannot be adjusted, which limits the application range of the annular loop to some extent. Therefore, a high strength annular sling is proposed to solve the above problems.
